Abstract

The spin vector \(\vec {J}\) of a hadron is constructed by adding the spins of the constituent quarks and their angular momenta \(\vec {\ell }\). For \(q\overline {q}\) mesons the total quark spin is \(\vec {s} = \vec {s}_q + \vec {s}_{\bar {q}}\) and \(\vec {J} = \vec {\ell } + \vec {s}\).
